Description
The Rear Delt Fly is a classic exercise where the torso is bent forward and dumbbells are raised to the sides, isolating the rear shoulder muscles. Also known as the Reverse Fly. Raising the arms to the sides with elbows kept slightly bent maximizes the activation of the posterior deltoid muscle. It also works the middle trapezius fibers, rhomboids, and upper back muscles. It is one of the classic bodybuilding movements and is critical for shoulder balance. It is highly effective for posture improvement, shoulder health, and rear delt development. When performed regularly, it provides significant improvement in rear delt hypertrophy, upper back development, and posture correction.
